BACKGROUND Mechanisms underlying the inverse relationship between height and cardiovascular mortality are unknown but could relate to central hemodynamics. We sought to determine the relation of height to central and peripheral hemodynamics, as well as clinical characteristics. METHODS The study population was comprised of 1,152 randomly selected community-dwelling adults (aged 67.7 ± 12.3 ye...

Although shoreface nourishments are an increasingly interesting option for coastal managers to counteract coastal erosion, their design is often highly empirical. A better understanding of the way shoreface nourishments interact with the initial beach profile may help to reduce the degree of empiricism in nourishment design. Literature study has shown that numerical modelling is commonly used t...

Catalytic waves obtained from the perchloric acid-soluble fraction of serum in the presence of hexaminecobalt trichloride appear to conform to a Langmuir adsorption isotherm. Wave heights for sera from patients with untreated urological cancers significantly exceed those from normal subjects. In general, treatment with diethylstilbestrol decreased the wave height. Effects of some other chemothe...

A shadowing-analysis-based algorithm is modified to estimate significant wave height from shipborne X-band nautical radar images. Shadowed areas are first extracted from the image through edge detection. Smith’s function fit is then applied to illumination ratios to derive the root mean square (RMS) surface slope. From the RMS surface slope and the mean wave period, the significant wave height ...

The analysis of wave breaking in shallow water has been on-going for almost 150 years. Numerous research papers have been published that investigate methods to predict breaking conditions and the geometric characteristics of breaking waves. This study presents a novel, safe, and low cost method to extract breaking wave properties from irregular waves in the surf zone, using optical and in-situ ...

Journal of Coastal Research, 21(3), 522–534. West Palm Beach (Florida), ISSN 0749-0208. The widely accepted assumption that the equilibrium beach profile in the surf zone corresponds with uniform waveenergy dissipatio...

Spaceborne active radar remote sensing, e.g., radar altimeter (RA) and synthetic aperture radar (SAR) have been playing an important role in the validation of numerical wave models, particularly in open ocean. Most forecast centres also use altimeter data in the wave data assimilation process. In this paper we present validation results based on the newly developed CWAVE_ENV algorithm. SAR wave...

The scattering characteristic of paraxial gaussian beam from two dimensional dielectric rough surfaces is studied in this paper. The modification of the Kirchhoff approximation theory for rough surface scattering by an incident gaussian beam instead of a plane wave are developed based on conventional Kirchhoff scattering theory and plane wave spectrum expansion method. The coherent and incohere...

[1] Ocean waves incident on coasts generate seismic surface waves in three frequency bands via three pathways: direct pressure on the seafloor (primary microseisms, PM), standing waves from interaction of incident and reflected waves (double-frequency microseisms, DF), and swell-transformed infragravity wave interactions (the Earth’s seismic hum). Beamforming of USArray seismic data shows that ...
